FLOOR-INDICATING MECHANISM FOR ELEVATORS.

To all whom it may concern.-

Be it known that I, FREDRICK F. CLoUsER, a citizen of the United States, residing at 'St. Louis, in the State of Missouri, have invented certain new and useful Improvements in a Floor-Indicating Mechanism for Elevators; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in theart to which it appertains to make and use the same.

The object of the invention is to provide simple and eflicient means whereby the floors or stations at which the several passengers entering an elevator car desire to alight may be indicated to the elevator operator without necessitating conversation or calling out of the numbers of the floors or the questioning of the passengers by the operator and the like, and under conditions whereby mistakes or forgetfulness or inattention upon the part of the operator may be avoided and hence loss of time to the passengers prevented, and also whereby the friction and misunderstandings frequently occurring between the passengers and the operator may be eliminated; and with these objects in view, the invention consists in a construction, combination and relation of parts of which a typical embodiment is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of the interior of the elevator car in which is arranged an indicator mechanism constructed in accordance with the invention.

Figure 2 is a diagrammatic view showing the passenger andoperator indicating members and the connections between the point ers thereof.

Figure 3 is a transverse horizontal sectional view of one of the indicator members.

Figure 4 is a top plan view of the bell crank levers and the wires or cords connecting'the same.

The apparatus consists essentially of a passenger indicating member 10 and operai respective floors or stations at which the elevator car is adapted to stop either to receive or deliver passengers, and a series of mov-- able pointers 12, pivoted as at 15 in the construction illustrated for movement respectively from their normal or neutral posi- Speeification of Letters Patent.

tions, represented on the scales by the naughts or ciphers to respectively designate numbers or other characters representing the floors or stations. One of these indicator members is located adjacent to the doorway 15 or means of entering and leaving the elevator car with a series of grips or finger holes 14 carried respectively by the pointers of said member within cflnvenient reach of a passenger entering the car, so that each passenger as he enters may press one of the finger holds or operating elements corre sponding with the floor or station at which he desires to alight. The other or operator indicator member 1s arranged adjacent to and within convenient view of the operator and the pointers thereof are also preferably provided with operating means or finger holds 14 by which the operator may respectively return the pointers to their neutral or normal positions after having passed the floors to which they respectively relate. i

The operating elements or pointers of the passengers indicator member are respectively connected with the corresponding pointers of the operators indicator member as for example by the bell crank levers 15 and 16, wires or cords 17 and 18 extending respectively from said operating elements and the pointers to the bell crank levers, and wires or cords 19 connecting corresponding bell crank levers, said wires or connections being extended through suitable tubular or like housings 20 and 21 and a boxing 22 located overhead and out of the way of the passengers and operator occupying the car and also substantially out of sight. It will be obvious that the specific arrangement of the connections between the passengers and operators indicator members must be modified according to the respective relations and specific positions of the elevator car door and the operators station that the operating element of the passengers indicator member may be located within plain view and reach of the passengers as they enter the car so as to be operated in passing the indicator and without causing any hesitation or delay which would obstruct the entrance and interfere with the expeditious loading and unloading of the car. To limit the movements of the pointers 12, so as to prevent undue strain upon the wires 17 and 18 and so as to cause the pointers to come to rest at the proper character, stop pins 12 are located on opposite sides of the pointers as shown in Figure 2 of the drawings.

Having thus described the invention, what I claim is 1. A floor indicating mechanism for elevator cars having an operators indicator member provided with a scale of floor or station designations and movable pointers for indicating movement in relation thereto, a passengers indicating member having operating elements respectively designated and distinguishable to represent respectively the floors or stations at which the car may stop, and connections respectively between said operating elements and the pointers of the operators indicating member.

2; A floor indicating mechanism for elevators comprising an operators indicator member provided with a scale of floor designations and movable pointers for indicating movement in relation thereto, a. passengers indicating member provided with a scale of floor designations and movable pointers for indicating movement in relation thereto, and means connecting the respective pointers of said indicating members whereby the pointcrs of one of said members may be operated in but a single direction by movement of their corresponding pointers in the other of said members.

3. A floor indicating mechanism for elevator cars, comprisingan operators indicator member provided with a scale of floor designations and movable pointers for indicating movement in relation thereto, a passengers indicating member provided with a scale of floor designations and movable pointers for indicating movement in relation thereto, and means comprising flexible connections and bell cranks connecting the respective pointers of said members.

4. A floor'indicating mechanism for elevator cars comprising anpperators indicator member provided with a scale of floor designations and movable pointers for indicating movement in relation thereto, a passengers indicator member provided with a
